• Parts of a nucleotide
• Long chains of nucleotides are nucleic acids
• DNA
• Stores hereditary information to make proteins
• Held together by hydrogen bonds
• Types
• RNA, DNA

13
Chapter 2 Test Review

• Chemical Reactions
• Activation energy
• Energy needed to start a chemical reaction
• Reactants/products
• Compare Reaction 2
  and Reaction 3
• Why is reaction 3
  the lowest on the
  graph

14
Chapter 2 Test Review

• Chemical Reactions
• Glucose glucose maltose water
• What would be found at each point?
• Why is 2 higher than 1
• How would it look with an enzyme?

15
Chapter 2 Test Review

• Enzymes
• Substrate
• Molecule upon which enzyme acts
• Key
• Label
• Active Site
• Portion of enzyme where substrate can fit
• Lock
• Label

16
Chapter 2 Test Review

• Enzymes (cont.)
• Graph activity of an enzyme
• Inactive from 0-20C
• Active above 20C w/rate increasing steadily to
  40C, at which the rate is very high
• Above 40C rate decreases rapidly until
  temperature reaches 50C
• Above 50C - inactive
